Thank you Kent, from Canada

my son bought a non running w 123 1981 model 300d i new nothing about Mercedes or diesel i am proud to say thanks to you i now have some knowledge an i am not afraid to work on it.

Mercedes Source is the best! Love you guys

Sold my 85 dt before I found your channel, Kent. Watching your vidoes has given me the old car itch again! Thanks

I took my delivery valves out and cleaned them and now my cars idles really good

Very reasonable cost. Not a bad way to go about this.

Any idea how air could get into an injection pump though the delivery valves? I am chasing an air infiltration situation and wondering if the o-rings of the injector barrel could be at fault. No fuel leaks at all either.

Ken, love your videos! I have discovered a approx 1964 OM621 190Dc vehicle and taken the engine out. It has been sitting for 30 years! I noticed you do not have many videos on these old engines. My question is the injection pump appears to have a resevoir for oil? Should it be changed and what kind of oil would be best? Thanks Uriah the Dakotan

Hey Kent, I've got a 1979 300d manual that has some issues with shaking when letting off and giving it gas, the car just sputters for a second or 2 before picking up speed. Was told by mechanics that its a IP problem. What should I look at first?
